Abstract
The utility model discloses a pickling sheet for pickling a diode, which comprises a base plate of which the working surface is provided with a plurality of through holes, and a frame fixedly which is fixedly connected with the base plate and provided with a mounting through hole. The upper rim of the frame is higher than the working surface of the base plate. The upper rim of the frame and the working surface of the base plate are connected by an inclined plane or a circular plane. The pickled sheet of the utility model can prevent the diode from being damaged and improve the pickling quality of the diode, thus greatly increasing the reliability and the yield of the diode.
Description
Technical field
The utility model relates to a kind of utensil that is used for the pickling material surface, is specifically related to a kind of acid-cleaning plate that is used for the pickling diode.
Background technology
Having now needs to carry out pickling acquisition electrical property in the process of making diode, and the quality of the quality of pickling directly influences the electrical property of diode, the acid-cleaning plate that is used for the pickling diode at present is a shaggy substrate simple in structure, the workbench of substrate has several through holes of evenly arranging, workbench to around extended edge be higher than the surface of workbench, during use, behind the lead-in wire insertion through hole of operating personnel with diode, slowly pour acid solution into from a side of substrate again, all be immersed in the upper surface of diode in the acid solution, still can kish impurity and acid solution and use acid-cleaning plate surface after the water flushing and place, dead angle all around, this easily makes the diode of follow-up pickling be polluted, influence the pickling quality of diode, thereby greatly reduce the reliability and the rate of finished products of diode.
Summary of the invention
The purpose of this utility model is: a kind of acid-cleaning plate that can avoid diode to be polluted, improve the diode pickling quality when pickling is provided.
In order to achieve the above object, the technical solution of the utility model is: a kind of acid-cleaning plate, comprise substrate, and the working surface of described substrate has several through holes, also comprises the frame of fixedlying connected with substrate, and frame has the installation through hole; The upper edge of described frame is higher than the working surface of substrate, is connected by the inclined-plane between the upper edge of frame and the working surface of substrate or arc surface is connected.
Described substrate comprises workbench and connecting portion, and the workbench of described substrate is inserted in the installation through hole of frame, and the connecting portion pad of described substrate is under frame.
The connecting portion at described substrate two ends has the substrate installing hole respectively, and the connecting portion correspondence at described frame two ends has the frame installing hole, and pillar inserts substrate installing hole and frame installing hole, and frame is fixedlyed connected with substrate.
Described pillar is four.
Described frame is a rectangle or square, and the corner of frame has the arc transition face.
The beneficial effect that the utility model had is: because the substrate of acid-cleaning plate of the present utility model has fixedly connected frame, be connected by the inclined-plane between the periphery of frame and the working surface of substrate or arc surface is connected, during use, operating personnel put into the lead-in wire of diode the through hole of substrate earlier, again acid solution is slowly poured into from a side of frame, and make diode all be immersed in the acid solution, can carry out pickling to diode, after the pickling, utilize clear water to be easy to wash down acid-cleaning plate, make that the surface of acid-cleaning plate can kish impurity and acid solution, avoided diode to be polluted, the pickling quality of diode be can improve, thereby the reliability and the rate of finished products of diode improved greatly.

Embodiment
Below in conjunction with the embodiment that accompanying drawing provides, the utility model is described in further detail.
Shown in Fig. 1,2,3,4,5,6,7,8,9,10, a kind of acid-cleaning plate comprises substrate 1, and the working surface 1-4 of described substrate 1 has several through holes 1-1, also comprises the frame 2 of fixedlying connected with substrate 1, and frame 2 has the through hole of installation 2-2; The upper edge 2-1-2 of described frame 2 is higher than the working surface 1-4 of substrate 1, is connected by inclined-plane 2-3 between the upper edge 2-1-2 of frame 2 and the working surface 1-4 of substrate 1 or arc surface is connected.
Shown in Fig. 2,5,8,9,10, for the fastness that guarantees that frame 2 and substrate 1 assemble, described substrate 1 comprises workbench 1-3 and connecting portion 1-2, and the workbench 1-3 of described substrate 1 is inserted in the installation through hole 2-2 of frame 2, and the connecting portion 1-2 pad of described substrate 1 is under frame 2.
Shown in Fig. 2,5,8,9,10, in order further to improve the fixing between frame 2 and the substrate 1, the connecting portion 1-2 at described substrate 1 two ends has substrate installing hole 1-2-1 respectively, the connecting portion 2-1 correspondence at described frame 2 two ends has frame installing hole 2-1-1, pillar 3 inserts substrate installing hole 1-2-1 and frame installing hole 2-1-1, frame 2 is fixedlyed connected with substrate 1, and described pillar 3 is four.
Shown in Fig. 1,2,3,5,6,8,9,10, there is not any dead angle between the working surface for the periphery that further improves frame 2 and substrate 1, the not residual any metal impurities in surface and the acid solution of acid-cleaning plate behind the assurance pickling diode, described frame 2 is a rectangle or square, and the corner of frame 2 has arc transition face 2-4.
When acid-cleaning plate of the present utility model uses, the through hole 1-1 that puts into substrate 1 that the lead-in wire of diode is orderly, owing to be connected or the arc surface linking by inclined-plane 2-3 between the working surface 1-4 of the periphery of frame 2 and substrate 1, thereby effectively the acid amount is annotated in control, and make acid solution be no more than the periphery of frame 2, both guaranteed that acid solution soaked diode, guaranteed that again acid solution can not overflow, avoid the waste of acid solution, after the diode pickling finishes and takes out, wash acid-cleaning plate with clear water, can wash very totally, do not stay any dead angle.
